IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. L11.7341, dated February 23, 1364.

To all whom -z't may concern:

Be-it known that I, WILLIAM N. WHITE` LEY, Jr., ot' Springfield,in thecouuty of Clarke and State of Ohio, have invented certain new and useful Improvements in Grain and Grass Harvesters; and lI do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making apart of this specilication, in Which- Figure I is a top view of a` harvesting-ma- Fig. 2 is a vertical section at the line m mot Fig. 1. Fig. 3 is a vertical section at the line y y, Figs. l and 2. Fig. 4 is a perspective view ofthe combination-box detached from the machine; and Fig.5illnstrates two pinions,eitheroneofwhich may be used on the master-wheels pinion-shaft.

'Ihe aforesaid invention will best be understood from the following description ot' it.

To enableothers skilled in the art to make and use my invention, I will proceed to describe the modes in which I have practiced it, referring to the different parts in the drawings by letters, similar letters denoting the same parts in all the different views.

A is the main frame of the machine. B is the main driving and ground wheel. axle, hung in boxes a, a, and which have vertical slots` e c in them, through which the bolts b b pass that confine them ro the inward-projecting flanges of the sector-plates D D. Around the external face ot' B are projections t' for preventing its slippage. h is the internal driving-gear rim, and J the convex side rim between the external rim and the cog-rim h'.

The convex form vof the connecting-plate or side rim, as illustrated at Figs. l and 3 of the drawings, whether cast with or secured to the external ground-rim of the wheel B, causes the earth (and especially'when wet) to curl or roll away from said convex portion as it sinks4 Ois itsl l strueted the machine is also operated with less power applied and less wear and breakage ot' the workin g parts than as heretofore constructed, as seen at Fig. 4.

M is a metallic combination box, which is cast in such shape as to furnish suitable bearings for the shaftE and front end of the crankshaft O. The front end of one of the sectorplates D D is hung ou the projecting end of E and the other on the stud d, in line therewith. have a series of holes in an arc, the center kof which is the center of those in the small ends for bolts-one in each plate--that confine the frame thereto.

G is the piniou,driven by h', and of as many` sizes as is desired for getting the required number of reciprocations of the cutters.

S is the bevel-driver on shaft E, and s2 is the bevel-pinion on the front end of O.

H is a spring-shipper by which the pinion G is retained on E, and by which said pinion also is thrown in and out of connection with the clutch-pin h. On the bolt t,which confines the heel ofthe tongue to the main frame, is a pinion, G, otf a different size from those shown at Fig. 5 of the drawings. The slots o c in the boxes a a permit them to be brought nearer to or farther from the shaft E, so that h will I do not wish to be understood -as limiting my improvement in the construction of the main driving-wheel of a harvester to the mak ing of the ground-rim, the convex side rim, and the driving-gear rim all solid together, as illustrated; but.

Having described my improvement in said wheel,wh at I claim as new,and desire tosecure by Letters Patent, is--J Connecting the external or ground face of tially as described, for the purpose set forth'.
